first you would need to find out how much 11.3% of $1205 is which is $136.17. And since the interest is yearly you would multiply the $136.17 by the 11 years which would be $1497.87. Then you would add the amount that they borrowed to the interest that they would owe after 11 years which would be $1497.87 + $1205 = $2702.87. So after 11 years the total amount that must be repaid is $2702.87
Let x = second angle let x + 10 = first angle let 2( (x) + (x+10) ) = third angle. Since the interior of a triangle equals 180° then, Inputting the value of x gives us each angle.
second angle = 25° first angle = x + 10 = 25 + 10 = 35° third angle = 2( (x) + (x+10) ) = 2( (25) + (25+10) ) = 110°
